Abstract
A stick electrode for depositing an high strength weld metal bead on a workpiece where the yield strength of the weld metal is between 85 ksi and 125 ksi irrespective of the cooling rate. The electrode deposits weld metal having 0.80-1.85% by weight manganese, 0.25-0.50% by weight molybdenum, 1.25-2.50% by weight nickel, and less than 0.07% by weight carbon, wherein the ratios of the carbon, manganese and molybdenum are adjusted to provide a carbon equivalent in deposited weld metal in the range of 0.17 to 0.30 and preferably less than 0.22.
